#shorts Machining a 340 Buick V8 Engine Block @Jim's Automotive Machine Shop, Inc.

The 340ci Buick V8 was only manufactured in 1966 and 1967! In today's video we bore the block and surface the deck surfaces.

    • @roadmonkeytj i deal with a dmg mori that has a really bad issue with losing work offsets. I was like 15 parts into an order and hit start it just sent the turret to some point behind the spindle blowing the jaws off totaling the spindle bearing and blowing the locking mechanism out of the turret just making it free spin. Was amazing. My asshole created a black hole it puckered so hard.

    • @User Name I would believe it all ... I'm a CNC maintenance tech now and I get to repair all that damage lol. Worst was a lathe drive had gone bad an when when the servo reset was hit the machine is supposed to go home and slow to reference dog ... Instead this went full rapid and blew the tailstock off splitting the casting of the tailstock. Production is worse ... They ran a 1" chamfer tool (last tool) as a 4" facemill (first tool) ... Snapped it in half ... Ran the whole program then the 4" mill was ran as a chamfer tool ... It's a miracle they didn't rip the tombstone off the table

  • Ya I want you to build me a 6.0l vortec for my 2007 Chevy Silverado 2500hd 4x4. There is nothing wrong with it right now at all but I see your true passion for what you do. I love my truck and it still looks and drives like the day it was built. 195,000 roughly on it. I want to just make give her a new heart and some seious horsepower and still be legal in CA. Gonna look you up

  • How much of a difference in performance would changing the pistons size from .003 to .006 do?

    Drew ParishDrew Parish26 วันที่ผ่านมา
  • Do you sonic test the bores of the block before machining oversize? Never had much experience with Buick engines myself, I know some Ford and other GM engines can only be bored oversized so far safely before bore distortion becomes an issue

  • Why not just sleeve the one cylinder at .040 over?

  • Sorry for a dumb question but new to this, but when you order the pistons is the only way to make up from the size difference from stock to oversized custom/oversized pistons, or is there another way?

  • I thought you were supposed to match pistons to the bore, so you buy the pistons first? .06 is quite a size difference, and in some cases, the absolute bore limit of the block!

  • Nothing wrong with taking that specific block over .060 Its a solid cast iron block! Now with our Honda B series blocks we can go as much as .040 over as long as it's a n/a motor. If not then .020 is all we can bore

    Jim HiscottJim Hiscottหลายเดือนก่อน
  • So if you’re taking material away, doesn’t that create space in the cylinder for compression to escape? I’m fascinated by this.

    Peter KentonPeter Kentonหลายเดือนก่อน
    • That's why he says oversized pistons. You get bigger pistons to compensate for less material

  • When I was younger dad taught me that once you get past .030 over,you get past the case-hardening and shorten the life of a rebuild.That was 40 years ago,is it still like that? When I did my 71 hilux I had it sleeved but the shop said it was past going any more over

    Joe DoyleJoe Doyleหลายเดือนก่อน
    • Are you jealous that we are bymathematic? Inches/millimeters who cares?

      Mixed Signal DrumsMixed Signal Drumsหลายเดือนก่อน
    • We use whatever the engine was designed in. In this case, an American engine from the 1960's, it was designed in inches. As such, it makes the most sense to use inches for all of our measurements. When we work with an engine that was designed in metric units, we use metric units for our measurements. While units matter, it's honestly pretty irrelevant to the work at hand. I could use football fields, light-years, hands. It doesn't matter as long as you understand conversion factors.

  • I have a question if you don't mind I have a 91 Tran am with the TPI 305 The guy I bought the car from hands me a box of 0.30 piston would that make the 305 a 306??? Or 308 I don't know if it be worth the rebuild or not the most I've found wrong with the car is valve stem seals with the touch of blow-by

  • I've seen a few engine block machining videos, but I've never heard tell of the bore being perfectly square to the crankshaft. What exactly does this mean?

    datgamerboy123datgamerboy123หลายเดือนก่อน
    • Ah, I think I know what you mean. Take the center axis of the bore, and the center axis of the crank, and intersect them. At the intersection should be a 90° angle, correct?

      datgamerboy123datgamerboy123หลายเดือนก่อน
    • The centerline of the crank represents one axis and the centerlines of the bores represent another axis. they should be 90 degrees from each other. If they are not, the piston will wear heavy on one side and there will be an airgap on the opposite side

      Shaun HensleyShaun Hensleyหลายเดือนก่อน
  • So let me get this right ..you were cutting at 40 but could not achieve that so u cut at 60 now needing new pistons but isn't that way better over all for both the owner and car ..bigger piston bore equals way more bang for your buck which in term means a lot more displacement and extra power ...have I got this right !!

    Ger 808Ger 808หลายเดือนก่อน
    • @Paisley Prince ok cheers buddy wasn't sure always heard when u widen a cylinder and add new pistons and rings u get more power ..my bad ...cheers for that

      Ger 808Ger 808หลายเดือนก่อน
    • No. The additional displacement is negligible and 060 over means that block most likely will have to be sleeved at the next overhaul or be disgarded.

      Paisley PrincePaisley Princeหลายเดือนก่อน
  • I know yall don't just use a Starrett 98 to check how level it is. What is that thing like .002" over 12"?

  • I have a bad habit of over thinking things. OCD perhaps. When using a level, can you get a bad reading if your deck is warped?

    Milton RosarioMilton Rosarioหลายเดือนก่อน
    • I think the level is just used to double check or give an approximation because a bubble isn't that accurate. The deck has to be flat in reference to the crank at 45 degrees so I'm guessing there's a much more accurate way than a level to set that up.

  • Could you just put a sleeve in that one cylinder and keep them at 30,000 or 40,000 either way just a question from an Novice

    Willie BulletmanWillie Bulletmanหลายเดือนก่อน
    • Because you would have to take out more material to put a sleeve in than it would be to just bore it to .060" over.

  • Do you ever use torque plates when boring the cylinders? An Aerospace machinist enjoying what you do here.

    Angry TwizzlersAngry Twizzlersหลายเดือนก่อน
    • @Jim's Automotive Machine Shop, Inc. that would be an interesting test to see.

      Angry TwizzlersAngry Twizzlersหลายเดือนก่อน
    • We don’t use a torque plate when boring, only when honing. Boring is meant to be a “roughing” process, so in my opinion there wouldn’t be any benefit to a torque plate during boring as any distortion will be fixed during honing. If someone has some reliable evidence that says otherwise I’m all ears, but from my own experience I don’t think it’s needed during boring.

    • I kept thinking that but I guess the end user will get to enjoy a little more parasitic drag.

      Bryce AugustsonBryce Augustsonหลายเดือนก่อน
  • Just a humble observation here but at .060" over would it have not been better too to press in 8 sleeves to keep it nice and stout and closer to the original measurements? How much casting material is still left around each cylinder at this point that any cylinder may be prone to a crack is the reason why I ask? Under no way to critique the work, HELL NO, great work!

    JT GJT Gหลายเดือนก่อน
    • @RMinOZ1 Ouch, I did not stop to think what each sleeve (the process and sleeve) would end up costing?

      JT GJT Gหลายเดือนก่อน
    • I like your theory, but at $100 bucks a pot, that's one expensive block, eventually.

  • How often do you need to service the mill for decking blocks? Does the cutting tool last 'X' amount of passes before it must be replaced, or does it stay sharp for years?

    Dave OsbunDave Osbunหลายเดือนก่อน
    • They wear out as any tool would sometimes slowly sometimes instantly depends on the work. Im guessing these are cbn or carbide button inserts.
